Referring to the drawing, A designates the base or combined floor late and ironing plate of the sad iron, the oor'plate 'cons'ti side of the floor. plate 15 for. the admission of air into the space between the ironing plate 16 and the floor plate. 15. The slot or air, inlet opening 18 extends around the.

sides and rear end or heel of; the sad iron and is closed at the front or. point where the rim. flange. 17 is. united with the floor. plate 15. l

The floor plate 15 and the ironing plate 16 are united at intervals by parallel pads or webs 20, which are formed integral with thetop and bottom sides. of the ironing plate and floor plate, respectively. The. pads s 20. c ns tut m ans. f r. ondu ing heat from the floor plate. Ofi the sad ironto he. roni g. p ate. her of. These. heat. conducting pads or we'bs are. parallel' to, one another and spacedv apart to, leave ai'r. pas,- sages e n m. nd; he nnerendsot the heat conducting webs 20'are also spaced apart to leave air passages 22 at the center e en .6 plates ndi Howev two of the webs or pads 20 are united at the center and provided with a recessed opening to receive the threaded lower end of a post or stud 23 which constitutes a portion of the means for securing the other parts of the sad iron to the base A. The heat conducting pads or webs are joined to the rim flange 17 by integral narrow neck webs 24 so as to form wide months 25 at the air inlet passage 18 for the lateral air passages 21.

The floor plate 15 has two rows of rectangular openings 26 therein on opposite sides of the longitudinal center line thereof and directly above the spaces 22 within the 1101- low base. These apertures or openings 26 are outlets for the air which enters the hollow base through ths slot 18 at the margin thereof. The floor plate 15 also has a circular opening 27 therein through which the post 23 passes. This opening 27 also per mits the air to pass up into the hollow body of the sad iron. Two parallel walls 28 are formed integral with the upper side of the floor plate 15 and extend upwardly therefrom and also extend along the outer sides of the rows of apertures 26.

A burner B is mounted upon the upper side of the floor plate 15 and consists of a hollow casting which is provided with an 4 opening 281 through which the post 23 extends. The burner B also has a hollow chamber 29 formed by the side walls 30, the bottom wall 31, the rear wall 32 and the top wall or roof 33. The rear wall 32 is provided with a threaded opening 34 to receive the threaded end of a pipe or conduit 35 through which combustible material is delivered to the chamber 29 of the burner. The bottom wall of the burner has two rows of outlets 36, each inside of the lower edge of the side walls 30. These outlets discharge the combustible material on to the top side of the floor 15 and outside of the upwardly extending walls 28 at the sides of the rows of air inlet apertures 26. The walls 28 serve to cause the entering air to issue upwardly from the apertures 26 against the under side of the bottom 31 of the burner and then flow outwardly to supply air for combustion of the gas and air flames issuing from the outlets 36. The burner B tapers forwardly as shown in Fig. 3 and the side walls 30 thereof slant from the upper wall 33 to the lower wall 31. At or near its lateral edges the burner B also has two depending flanges 37 extending downwardly toward the floor 15 to deflect the flame and hot gas against the floor 15. The space beneath the burner and within the depending flanges 37 constitutes a flame chamber open at its base, the flanges 37 serving to deflect the flame against the floor of the sad iron. The

opening 281 which accommodates the post 23 is surrounded by a circular wall 282 which'prevents communication between the opening 281 and the burner chamber 29.

The front end of the burner B has a downwardly extending part 38 which forms a leg to support that end of the burner and the rear end of the burner is provided with two legs 39 at opposite sides thereof. The legs 38 and 39 support the burner and serve to locate the flange 37 the required distance above the floor plate 15. The upper end of the post or stud 23 is threaded as shown in Figs. 2 and 10 and is adapted to receive a nut 40 which is adapted to be screwed down on to a washer on the upper side of the roof of the burner to fasten the burner in position within the hollow body H.

The pipe or conduit 35 which leads the combustible mixture to the burner B is threaded at its outer end and carries a gas and air mixing Bunsen device K which has a gas and air passage 41 at the end which is connected to the pipe 35 and a gas passage 42 at the end to which a flexible gas tubing may be connected. The wall of the gas and air passage 41 has a series of air inlets 43 therein, and the two passages 41 and 42 are connected together by a restricted gas passage 44; the end nearest the gas passage 42 terminates in a preferably tapering part 45 extending into the gas passageway 42, thus forming a depression or pocket or trap for impurities between the part 45 and the walls of the gas passageway 42 to prevent the restricted gas passageway 44 from becoming clogged. The construction of the device K provides for a thorough 1nixture of gas and air for the burner and a means to delay or entirely prevent impurities clogging the restricted passage 44.

The burner B is inclosed by a hollow shell or body H which is open at the top and bottom and" also has a cutaway part 46 in one side and at its upperedge to let out the proclncts of combustion at this lateral edge. The sides of the body H slant upwardly and inwardly and approximate the inclination of the outside of the side walls 30 of the burner. The upper side of the floor 15 of the iron has two rim flanges 47 which meet at the point of the sad iron. The upper side of the floor 15' also has two walls 48 within the rim flanges 47 and spaced therefrom to provide wide grooves 49 to receive the lower edges of the sides of the body H and the two, walls 48 are for the purpose of conducting heat from the flames of the burner to the floor 15. The rear wall of the body H has an opening 50 therein which is adapted to be closed by a door D. The opening 50 is provided to admit the pipe 35 which supplies the combustible mixture to the burner, and is also provided so that access may be had to the inside of the body H to light the combustible gases at the burner B. The cutaway part 51 of the door is arranged so that the door D may be closed and opened with the pipe 35 in position and without interfering with the latter.

tee-gas plane of the door and when the door is iii positionthey bear against the inside surface of the rear wall of the body and areheld in place bythelegs39ofthe burner -B which are spaced away from the inside ofthe rear Wall of the, body H to provide recesses to. receive the hinge pivots 52. In Figs. 4 and 5 I have shown other ways of holding the hinge pivots 52of the door in place. In Fig'; 4 the floor 151 is provided with bosses or projections 152 integral withits uppers'id spaced adistance fromthe rear wall of the bodyI-I toprovide therecess forreceiving the hinge.pivots 52. In Fig. 5 the hinge pivots52 of the door D fit in and areheld in place by recesses 153 in the side] wall of the body H. In Fig. 11 the legs 39 ofthe burner B are shown asprovided with, rearwardly extending projections 391 a'distance above the floor 15 to" forth recesses 392 to receive the pivot pins of the door and holdthe latter in place in the door opening 50. The

rear side of the door D is provided with a raised part 5 lc whichterrninates at its lower endin a knob 55. Atthe side of the dooron the rear wall of-theholl'ow body H there is a. latch 56 pivotallyconnect'ed thereto at and which is adaptedto swing downwardly over the'inclined surface 54 against the boss or projection 55 to lock the door Din closed.

position. When thedoor is to be opened the latch 56 is raised and the door will swing outwardly and downwardly on its pivot pins 52. V A knob or handle 58 is alsopro vided at the upper-edge of'the door.

A cover plate 60 i-ests en projections 61 at the upper edge of the body Hand theseprojections hold the cover plate 6 0 a slight dis tance above the upperedge of the body H to provide the outlets 62; for products of corn bustion. As shown in Fig.2 l0, the cover plate6'0 extends laterally farther to one side of the body H over the cut-out part 46 so as to form a deflector-for the heat escaping through the opening4c6. Thecover' plate 6.0 is also provided, with an opening through which the post 23 passes and Supports the asbestos insiilating plate 68. The asbestos plate 68 for which might be sii-bstitnted an air-space is-hel'd in place by an upwardly extending riin flange 64 on the aver, plate 60. A, second plate '65 i's p evidedwith an openingto fit over thepqseee andfits the rim flange 64; andseats upon the asbestos heat insulation 'Thesecond 6-5, is provided with a pluralitylofknobs 68lfon its upper side to spafce the handle plate 66 from the said secondiplate 65',"but the space thus form-ed may be filled with insulating mate rial. The air space h'? between theplates 65 and 66 is within the riin (SS-which holds the handle plate 66 in place. The handle plate has a handle 69 formed integral therewith andalso has a depression 70 in its up per side which surrounds an opening 71 through which the upper end of the post 23 eirtends. The depression 70 is designed to receive the nut 72" which fitson the upper end of the post 23 and when screwed into place holds the hollow body H and the parts resting on it in place. Since the nut 72 is counter-sunk a certain distance in the depression 70 there will be plenty of space heheath the horizontal part ofthehandle 69 to prevent a liuinanhand, when grasping the handle, coming in contact with the upper iehd of the post 23 which is apt to be quite iot. l
